About sir kensington’s

How did Sir Kensington's start? How long has it been around?

Sir Kensington's was a lofty dream shared by Mark Ramadan and Scott Norton during their undergraduate studies. The two noticed the food world was changing for the better, but that condiments hadn't quite caught up yet. Mark and Scott set out to change that. They left their corporate jobs and took on their dreams by officially launching Sir Kensington's in 2010.

I'm interested in having Sir Kensington’s sponsor an event. How do I do that?

Do I have to refrigerate my SirKensington’s condiments after opening?

Our eggless Fabanaise should be kept refrigerated at all times, including before opening. All of our other delicious products should be refrigerated after opening. We preserve good taste, not preservatives!

How long can I enjoy my condiments after opening?

After opening, store your condiments in the refrigerator. For best taste and quality, we recommend consuming mayonnaise and ranch within 1 month, ketchup within 2 months, and mustard within 3 months after opening.

Is Sir Kensington's Kosher?

All of our retail products are Certified Kosher by the Orthodox Union.

Are your condiments organic?

We are very excited to have launched an Organic Classic Mayonnaise. Every Sir Kensington's product is Non-GMO Project Verified, and uses the best ingredients to make the best tasting condiments. Sometimes that means using organic ingredients, as with the use of organic sugar. Other times, like with our tomatoes, it means sourcing the best-tasting, non-GMO ingredient we can find.

Does your mayonnaise contain dairy?

No, our mayonnaise is dairy-free.

Why is there sugar in your mayo?

We use trace amounts of sugar to balance the acidity of the lemon juice and achieve the well-rounded flavor you love. Our mayonnaise contains .25 grams of sugar per serving. By FDA standards, this trace amount does not register as a per-serving quantity. As a result, it is listed as 0g.

What do I do if my mayonnaise appears separated?

If your mayonnaise appears to be separated, do not eat it. Because Sir Kensington's does not use artificial stabilizers or preservatives, the contents may separate when exposed to freezing temperatures. Please contact us if you recently purchased a mayonnaise that may have separated.

What type of eggs do you use in your mayonnaise and ranch?

We proudly use Certified Humane Free Range eggs in our products, sourcing them from cooperatives of family farms in and around the Eastern Iowa region. These standards are more well-defined than the USDA Free Range definition, specifying the amount of time and space hens need access to the outdoors. Certified Humane production never uses cages and ensure hens are provided the conditions necessary to engage in natural behavior so they can be the plucky animals they're known to be.

Are the eggs in your mayonnaise pasteurized?

Yes, the eggs in our mayonnaise are pasteurized.

What kind of oil do you use in your Classic Mayonnaise, Fabanaise (vegan mayo), and Ranch lines?

We use 100% sunflower oil in our products. The sunflower oil in our Mayonnaise, Fabanaise, and Ranch is mid oleic. The oil is extracted from the seeds of the sunflower using a solvent. The sunflower oil in our Organic Mayonnaise is high oleic and expeller-pressed. All of the sunflower oil we use is refined. Each of these products does have a version available made with 100% avocado oil.

What oil do you use in your Avocado Oil Mayonnaise, Avocado Oil Fabanaise, and Avocado Oil Ranch?

The oil used in our Avocado Oil Mayonnaise comes from two varieties of avocado: Hass and Fuerte. Avocado Oil is made by pressing the pulp of the avocado fruit, without the skins or seed.

How much sugar is in your ketchup?

Our ketchup has 2 grams of sugar per serving. We're proud to use organic cane sugar, never high fructose corn syrup.

Could you tell me more about the tomatoes you use in your ketchup?

We source our tomatoes from a collection of farms in Central and Northern California. Our vine-ripened tomatoes are processed within 4 hours of being picked to ensure the ultimate freshness and the best-tasting flavor.

Where do your mustard seeds come from?

Ingredients & allergens

Are your condiments gluten-free?

Yes, all of our condiments are Gluten Free. Our facilities have processes in place to prevent cross contamination of products. All of our condiments undergo routine gluten testing and are tested at under 10 ppm.

Do your products contain soy?

All of our products contain no soy.

Do you use high fructose corn syrup?

Never! Our products are sweetened with organic sugar; never high fructose corn syrup.

Why do you use sunflower oil instead of other alternatives?

We choose to use sunflower oil because it is true to the classic French tradition of making mayonnaise, and we believe it produces exceptional flavor. While Canola Oil is most often used in conventional mayonnaise, it is typically derived from GMO seed. Our 100% sunflower oil is only extracted from non-GMO sunflower seed.

What kind of vinegar do you use?

We use white distilled vinegar derived from sugar and non-GMO corn for our Mayonnaises, Fabanaises and Ranch. We use Organic white distilled vinegar dervied from sugar cane for our Mustards and Ketchups.

Do your products contain peanuts?

No, our condiments do not contain peanuts. They are produced in a peanut-free facility.

Do your products contain tree nuts?

Our condiments do not contain tree nuts, but they are produced in a facility with tree nuts. While our team has strict cleaning and allergen programs in place to minimize the possibility of cross-contamination, any item produced on a shared line runs a slight risk of contamination. Customers with severe allergies should take this into account when deciding whether to consume our products.
